In the late 1970s, she did various voice-overs for a number of cartoons, which would continue throughout her career. She was hired to replace Ann Risley when Saturday Night Live was being retooled in 1981 following Jean Doumanian's disastrous stint as executive producer. However, O'Hara quit the show without ever having made an appearance on it, primarily due to her shock after witnessing a long, loud diatribe by SNL writer Michael O'Donoghue. Her SNL position was then given to fellow Canadian Robin Duke, who had also replaced O'Hara for a season on SCTV.

She had an unusually dramatic role in The Last of the High Kings as a staunch Irish nationalist in 1970s Dublin.
